I am sending a message from my windows application to a private queue, which is working fine. Now I am trying to set time expiry before sending the message from windows application.
Also how long will msmq message stays in queue? 4 days?

What I have tried:

I tried this, not even sure if it is correct way of doing it:

msMq.MessageReadPropertyFilter.TimeToBeReceived = true;
               System.Messaging.Message msg = msMq.Peek(TimeSpan.FromSeconds(10.0));
               msMq.Send(job);

Thanks!
